摘　　要：经典的Chord模型中为维护Chord环路由信息而周期性执行的Stabilize操作产生了大量的消息转发。提出一种改进的Chord模型,通过使用优化的双向Finger表,使得只在节点加入或离开时才进行路由更新,降低了消息转发的开销,同时优化了路由定位算法。In order to maintain the latest routing information in Chord ring, in its typical model the Chord system has to execute a ＇ Stabilize＇ operation periodically, which leads to mass forward messages. This article introduces a modified Chord model using optimised bidirectional Finger tables. It informs particularly nodes to update their routing table only when a node joining or leaving, thus it reduces the message forwarding cost and also optimises route locating algorithm.
